CROSS-REFERENCE TO RELATED APPLICATION INFORMATION

This is a continuation of U.S. application Ser. No. 16/253,542, filed Jan. 22, 2019, which is a continuation of U.S. application Ser. No. 15/922,165, filed Mar. 15, 2018, now U.S. Pat. No. 10,231,090, issued Mar. 12, 2019, the entirety of each of which is incorporated herein by reference.

BACKGROUND

Mobile devices, such as smartphones and tablet computers may include a variety of sensors, such as a camera and a Global Positioning System (GPS) receiver. A mobile device may allow a user to install and run different types of applications (or “apps”) on the device.

One category of mobile apps is note-taking apps, which allow a user to create and share textual or graphical notes. Some note-taking apps automatically archive notes by date. However, if a user creates hundreds or thousands of notes, it can be difficult to locate a specific note in the archive, even if the user recalls when (or approximately when) the note was created.

Another category of mobile apps is photo apps for taking and sharing pictures. When a user takes a picture with the mobile device's camera, the photo app may automatically tag the picture with the device's current location (e.g., using the GPS receiver).

DETAILED DESCRIPTION

According to some embodiments of the present disclosure, a system for location-based note sharing allows users to create and share notes using a mobile app. A user of the app can “drop” notes at their current location and view notes that were dropped by other users within a user's geographic vicinity. In some embodiments, the mobile app allows the user to search for notes by location, date, and/or keyword. The user can choose to have their notes be kept private, shared within a one or more other users (“friends”), or made public. In some embodiments, location-based notes may be analyzed to identify trends among users of the system. In some embodiments, an advertiser can directly market to users that dropped notes within a given geographic area.

FIG. 1 shows a system 100 for location-based note sharing, according to some embodiments of the present disclosure. The illustrative system 100 includes one or more user devices 102 a, 102 b, . . . , 102 n (102 generally) coupled to a server device 104 via a network 106. The service device 104 may include a sharing module 108, a search module 110, a trends module 112, a direct marketing module 114, a friends module 116, and a database 118. The various components of the system 100 may be connected as shown in FIG. 1 or in any other suitable manner. The system components may be connected by one or more wireless or wireline computer networks.

User devices 102 may include smartphones, tablets, or other mobile devices configured to install and run user applications (“apps”). In some embodiments, a user device 102 may run a location-based note sharing app that communicates with server device 104 to store notes and to retrieve notes shared by other user devices. In some embodiments, one or more of the server modules 108-116 may include an application programming interface (API) via which a user device 102 can issue specific types of requests discussed herein below.

Sharing module 108 may be configured to store newly created notes in the database 118. A user device 102 may send a request to the sharing module 108 to store a new note. The request may include the contents of the note, such as text and a picture, along with the location where the note was created and the date/time when the note was created. Location may be specified, for example, as a pair of longitude and latitude values.

In some embodiments, a user may specify sharing preferences when creating a note. Accordingly, the request sent to the sharing module 108 may include, for example, a share level indicating whether the note should be “private,” “public,” or “shared.” A private note may only be viewed by the user that created the note. A public note may be viewed by any user of the system 100. A shared note may be viewed by the author of the note and by any of their “friends” as defined within the system 100. In some embodiments, each user has a list of friends defined within the system 100 and a shared note may be viewed by anyone in that list.

Database 118 may include non-volatile memory configured to store data used to store and share location-based notes. In some embodiments, the database 118 may include a relational database having one or more tables to store users, notes, friends, searches, and advertisers. The tables may be indexed to facilitate searching for stored notes. For example, the notes table may be indexed by location, date, and keyword to allow respective location-, date-, and keyword-based searching. In some embodiments, the database 118 uses a database schema, such as schema 800 described below in the context of FIG. 8. In some embodiments, the database 118 includes a file store wherein pictures or other non-textual note content may be stored.

Search module 110 may be configured to process note search requests. In some embodiments, a search request may specify a geographic area over which to search. The geographic area may be specified, for example, using a center location (e.g., a latitude/longitude pair) and a search radius. In this case, the search module 110 may query the database 118 for notes created within the circular area defined by the center location and search radius. In some embodiments, search module 110 handles date-based and keyword-based search requests. In addition to specifying a geographic area to search, these types of search requests may further limit the search results based on a given date range or keyword, respectively. The search module 110 may restrict its queries to notes that were created by the user making the request, notes that were shared by a friend of the user, and notes that are public.

Trends module 112 may be configured to identify trends within particular geographic areas based on notes stored within the database 118. In some embodiments, a trend is identified by searching for notes within a common geographic area and within a predetermined time period. For example, a trend may include ten (10) notes created within the last hour, all within some relatively small geographic area (e.g., a bounded geographic region of one 10,000 square feet). The predetermined time period may be, for example, the last hour, last 24 hours, or last 48 hours.

In some embodiments, the trends module 112 is configured to handle trend requests, which are requests to identify trends. In some embodiments, a trend request may specify a geographic area and/or a time period. The trends module 112 may analyze notes stored in the database 118 to identify trends within the specified geographic area and/or time period.

In some embodiments, background processing may be used to periodically and/or continuously identify trends within selected geographic areas. The results of the background processing may be stored in the database 118 and/or in memory and used to process subsequent trend requests.

Direct marketing module 114 may be configured to identify users that have created notes within a given geographic area and time period, and to send targeted advertising to those users. In some embodiments, an advertiser may use a user device 102 to interact with the marketing module 114. For example, an advertiser may install a direct marketing app on their mobile device 102. The direct marketing app could be part of the location-based note sharing app or a separate app. The direct marketing module 114 may receive a request to send direct marketing to users that have recently created notes within a specified geographic area. The direct marketing module 114 may then, for example, send a push notification, an email, etc. to each of those users.

In some embodiments, the trends module 112 and/or direct marketing module 114 may allow a geographic area to be specified descriptively within a request. For example, a user may specify a street address, a business name, or the name of a landmark. For example, an advertiser may specify the name of a mall in order to target users who visited that mall. The modules 112, 114 may use a location database or a third party location service to translate the descriptive geographic area into latitude and longitude values which can be used to search for notes in the database 118.

Friends module 116 may be configured to manage lists of friends for users of the location-based note sharing app. The app may send requests to the friends module 116 to add or remove people from a user's friend list.
